You could probably create a new theme: https://github.com/element-hq/hydrogen-web/blob/master/doc/architecture/THEMING.md

I took this approach and created a new derived theme using this as a template: https://github.com/element-hq/hydrogen-web/blob/master/scripts/test-derived-theme/theme.json
However, I get this on the console: Error: Base manifest for derived theme at /assets/theme-neko.json not found!

        {
          "name": "Neko",
          "extends": "element",
          "id": "neko",
	  "values": {
            "variants": {
              "dark": {
                "dark": true,
                "default": true,
                "name": "Dark",
                "variables": {
                  "background-color-primary": "#36393f",
                  "background-color-secondary": "#404349",
                  "usercolor1": "#dcddde",
                  "usercolor2": "#dcddde",
                  "usercolor3": "#dcddde",
                  "usercolor4": "#dcddde",
                  "usercolor5": "#dcddde",
                  "usercolor6": "#dcddde",
                  "usercolor7": "#dcddde",
                  "usercolor8": "#dcddde"
                }
              }
            }
          }
        }

Am I doing something wrong here?

Could be wrong, but I think it can't find theme-element.json that you are deriving

In reply to @xhawk87:hawks-haven.co.uk
Yeh, but I am not sure why that would be the case. it's definitely loading that resource based on the network logs. I can't get a lot of debug information about what's going wrong as this is the release build in a production environment. Has anyone run this derived theme test recently?

In reply to @bwindels:matrix.org
Because of the "extends":" element" prop in your theme.

In reply to @xhawk87:hawks-haven.co.uk
If the "test-derived-theme" test works, then this should too, but it doesn't. So has anyone run the test?

In reply to @bwindels:matrix.org
I haven't. You can't run it?
